IMPROVEMENT IN SPRING-MOTORS..

Specification forming part of Letters Patent No.` 197,822?, dated December 4, 1877; application led I September 15, 1877.

To all whom it may concern:

Be it known that we, EnMoNn W. BROD- NAX and BENJAMIN COHEN, of Eutaw, in the county of Greene and State of Alabama, have invented a new and valuable Improvement in Motors vfor Fly-Brushes, Fans, and other articles; andwe do hereby declare that the following is a full, clear, and exact'description of the construction and operation of the same,

reference being had to the annexed drawings,

j The end wheel B oi' this train meshes with the pinion (l on shaft D, which has its bear ings in the side walls of a case, X, and the top wheel E meshes with the pinion F on shatt G. The ends of the shaft D project through the side walls of the case X, one end ofthe said shaft being provided with a ilywheel, H, having a crank-pin, h, and upon the other end is mounted a friction or brake wheel, I, upon the. periphery of which rests the brake K, which may be pressed against the wheel with more or less force by 'its handle K', inorder to regulate the speed of the apparatus, The shaft Gr has its bearings in standards g projecting upward from the frame of the train, and carries upon .one end a iiywheel, L, having a crank-pin, l, to which is connected4 a short pitman, M, which is also jointed to a reciprocating rod, N, extending upward through a guide-bearing, n, in the top of the case, and a guide, a', erected thereupon. From the ends of this case X double` or bifurcated standards O O project upward vand are provided with holes o o o for pivots or fulcrumpins of levers, which may be mounted at various heights upon said standards.

To the crank-pin h lof the ily-wheel H is connected a pitman, P, which plays through a guide-slot, q, in an arm, Q, projecting fromV the end of case X. In Fig. 3 this pitman is connected to a swinging cradle, R, and the or brush being arranged directly over the cradle.

When the spring is wound up by means of an ordinary key or winchfas shown by t,

(said spring being Vconnected with` the train, as is the ordinary motive spring of a clock.- train,) and the train is in operation, the iiyfwheel H reciprocates its pitman P, and gives a swinging motion to the cradle R, while at the saine time the flywheel L, through its pitman and the reciprocating rod N, communicates a vibratory motion to the iiy-brush for the purpose of keeping tlies away from the occupant of the swinging cradle, so that by this arrangement we have a combined cradle rocker or swinger and ily-fan.

Instead oi'to a cradle, the pitman P may be connected to the crank or ily wheel of a colfeemill, and the reciprocating rod N may be jointed to one end of a lever fulcrumed in one ofthe standards 0, and. having its other end `iointed to'the daslrrod of a churn; or the pitman P may be connected to the crank-pin of a belt-wheel arranged to drive a sewing-machine. f

Convenient methods of connecting the motor for the operation of any of the ordinary In testimony that we claim the above we have v hereunto subscribed our names in the presence of two witnesses.
